33 Warm Weather Energy Efficiency Tips


While MTEMC's rates are 20% lower than the national average, the weather can cause a high bill. We've put together a list of things that you can do to be more energy efficient during the hot weather.

  1. Set the thermostat to the highest comfortable temperature. Moving the thermostat up one degree could mean about a three-percent reduction in your electric bill.
  2. Keep air conditioner filters clean. Disposable filters should be checked regularly and replaced as needed.  Letting your filter go too long past its intended use could cause higher energy costs. Increased activity in the home, pets and home air leaks can shorten the life of the filter.
  3. Keep air vents clear of obstructions.
  4. Close the drapes on the sunny side of the house during the day.
  5. Leave storm windows and doors in place when the air conditioner is on.
  6. If you're gone for an extended period, adjust your thermostat higher to save energy.
  7. If you cool with window units, place them on the north side of the house when possible, clear vents of obstructions, shut doors to unused rooms, and close floor or wall registers used for heating.
  8. Run ceiling paddles fans on medium, blowing down in the summer.
  9. Be sure you have an energy-efficient electric water heater. Reference the energy label or where you purchased it for more information.  
  10. Set the water heater thermostat at 120 degrees. Always turn off the circuit breaker before you adjust the thermostat on an electric water heater.
  11. Insulate the pipes going into and out of the water heater tank. Add an insulated blanket around your water heater if it's an older model per manufacturer recommendations.
  12. Turn the water heater off when you're gone longer than a weekend.
  13. Wash full loads of clothes in the coolest water possible. Rinse clothes in cold water.
  14. A low-flow showerhead can reduce water use by up to 60 percent.
  15. Run the dishwasher only when it's full.
  16. Compact fluorescent or LED bulbs can replace incandescent bulbs in most table lamps and could save up to 70-80 percent in lighting energy, produce more light and last longer.
  17. For more light, use one large bulb rather than several small ones. A 100-watt bulb produces more light with less energy than two 60-watt bulbs.
  18. Use low-watt bulbs where lighting is not critical.
  19. Dimmer switches are actually smarter.
  20. Place floor lamps and hanging lamps in corners. The reflection off the walls will give you more light.
  21. Turn off all lights, TV's, stereos and radios if no one will be in the room.
  22. Keep the temperature between 35 and 38 degrees in the refrigerator and 0 degrees and 5 degrees in the freezer. Use a refrigerator/freezer thermometer to check the settings.
  23. Cool foods to room temperature before placing them in the refrigerator unless the recipe specifies otherwise.
  24. Place the refrigerator away from the stove, dishwasher, heat vents and direct sunlight. Follow the manufacturer's instructions on the amount of air space needed around the refrigerator.
  25. Keep the freezer full. The fuller the freezer, the less cold air you lose when opening the door. Keep the coils and seals clean can also save energy.
  26. Defrost manual-defrost refrigerators or freezers when the frost becomes 1/4" thick.
  27. Plan meals so several things can cook at the same time in the oven. Avoid opening the door until the food is done, unless the suspense is too much for you.
  28. While the microwave is great for re-heating leftovers, takeout foods or cooking a single dish, a conventional oven may be more economical if you're cooking several items.
  29. Baking or microwaving defrosted food uses one-third less energy than starting with frozen food.
  30. If you're going to clean your oven, use the self-cleaning cycle right after you finish baking. That will give the self-cleaning cycle a head start in heating the oven.
  31. Besides cleaning your lint filter after every load, make sure you dry full loads of clothes without overloading.
  32. Stop the dryer as soon as clothes are dry, or use the moisture sensor control to automatically shut off the dryer. Over drying wastes energy and sets in wrinkles.
  33. Dry loads one right after another. You'll use less energy because the dryer is already heated.
